PARTICLES COLLECTING APPARATUS

摘要

PURPOSE: A fine particle collection device is provided to reduce loss of wind pressure and to collect a fine particle in fluid while suppressing reduction of fluid. CONSTITUTION: A fine particle collection device includes a body(110), an inner body(130), a swirler(140) and a filter(150). A travel path of fluid is formed inside of the body. A travel path of fluid is formed inside of the inner body and the inner body is arranged inside of the body. The swirler is arranged in an upstream side of the inner body inside of the body, obliquely arranged in the moving direction of the fluid and guides the fluid to the inside of the inner surface of the body. The filter collects a fine particle included in the fluid passing between the inner body and the body. A Venturi unit(160) increasing a flow speed of fluid is disposed between the inner body and the body. A plurality of Venturi units are spaced apart with each other along the radial direction of the body.
